Core X Chroma Ethernet Issues

Periodically my internet connection goes down, and the Core X Chroma Gigabit ethernet link says "No Internet" in Windows. Cannot /release/renew IP address, it says timed out. All other devices on the network are fine. Previously I have resolved by using a different cable, then using the original after it starts working, reseating the ethernet cable, using a different port on the switch, but this time nothing is resolving it. It's detected in Windows, drivers installed, enabled, but just not able to transmit/receive. Bought a Razer Blade, mouse and Core X Chroma, and every one of them has failed within 2 years. I see a number of similar posts but they're all locked - has anybody had this issue resolved?
